Nagisa Ran, a third-year Shuetsu Academy student, leads the idol unit Eden under COSMIC PRODUCTION, overseeing sub-units Adam and Eve. His name, meaning "calm sand" and "rebellion," mirrors a personality marked by contrasts. Long silver hair flows into a ponytail, framing lava-red eyes and a tall, athletic frame that distinguishes him as Eden’s tallest member. Raised in isolation under the enigmatic Godfather, Nagisa was molded into an art object rather than a person, denied formal education and trained in idolcraft inspired by a mentor called "That Akehoshi." Following Godfather’s death, Hiyori Tomoe’s family sheltered him, teaching literacy and social norms. In Yumenosaki’s former unit fine, he adhered unquestioningly to Hiyori’s directives. Post-fine’s dissolution, Ibara Saegusa recruited them into COSMIC PRODUCTION, establishing Eden and sub-unit Adam. Publicly, Nagisa relies on Ibara’s pre-written scripts to navigate speech, yet privately critiques strategies lacking logic, offering calculated alternatives. His stage presence exudes icy authority, clashing with an inner yearning for peace and resistance to discord. Offstage, childlike curiosity drives pursuits like archaeology, experimental cooking, and perilous mountain climbs—impulsive ventures often requiring rescue by others. Social norms elude him due to his cloistered upbringing; he consults guides on etiquette and falters with names, as seen with Tsumugi Aoba. Yet loyalty to Eden and a playful private demeanor emerge as he adapts. A solo journey abroad eroded his Japanese fluency, while post-War Yumenosaki’s return revealed a school transformed, prompting reflections on past strife amid newfound camaraderie. Nagisa balances disciplined leadership with quiet idealism, prioritizing unity over solo acclaim in performances through supportive vocal harmonies. Encounters with Trickstar and former fine peers highlight his evolving views on legacy—honoring history while pursuing uncharted paths. Financial recklessness, marked by whimsical purchases, forced Ibara to enforce budgets, teaching Nagisa fiscal restraint and independence. His evolution weaves an enigmatic idol’s poise with earnest attempts at connection, blending regal detachment, fragile transparency, and steadfast resolve. Threaded through his journey are echoes of mentorship’s imprint, the quest for self beyond others’ designs, and the delicate dance between artistic persona and authentic identity.
